GRAPPLE FOR LI FTING LOGS.

SPECIFICATION forming part of Letters Patent No. 607,571, dated July 19,1898.

Application filed March 30.1898.

To all whom it may concern/.-

Be it known that I, ANDREW PAULSON, a citizen of the United States,residing at Snake, in the county of Marshall and State of Minnesota,have invented a new and useful Grapple for Lifting Logs, of which thefollowing is a specification. r

The invention relates to improvements in grapples for lifting logs.

The object of the present invention is to improve the construction ofgrapples and to provide a simple, efficient, and powerful one especiallyadapted for lifting heavy logs and capable of securely clampingthe sameand of preventing them from slipping or falling while being lifted. I

The invention consists in the construction and novel combination andarrangement of parts, as hereinafter fully described, illustrated in theaccompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a perspective view of a grapple constructedin accordance with this invention. Fig. 2 is a detail perspective viewof the top connecting-piece.

Like numerals of reference designate corresponding parts in both figuresof the drawings.

1 1 designate the sides or arms of a log-engaging grapple, and thesesides or arms 1, which are connected at their upper ends by a top pieceor frame 2, are provided near their lower ends with hooks or spurs 3,extending upward and inward at a slight inclination and adapted to imbedthemselves in a log below the center thereof, whereby the weight of thelog will operate to hold the sides or arms in engagement with the same,thereby effectually preventing a log from slipping or falling whilebeing lifted.

The upper ends 4 of the sides or arms are reduced and perforated, andthe'top piece or frame 2, which is substantially rectangular, isprovided at opposite sides of the device with projectingears 5, whichare perforated to receive pivots 6 and which'are located at oppositesides of the reduced upper ends 4 of the sides or arms 1, the pivotspassing through the parts and connecting them.

The sides or arms 1, which are. adapted to swing inward and outward onthe pivots 6, are provided at their inner edges with perfo- Serial No.675,773. (No model.)

rated enlargements, forming upper and lower eyes 7 and 8. The upper eyesare located a short distance below the top piece or frame 2, and thelower eyes are arranged a short distance above thespurs or hooks 3.

The upper eyes 7 receive short chains 9, which connect the upperportions of .the sides or arms 1 with a hoisting-chain 10 or othersuitable flexible connection, such as a rope or cable. Thehoisting-chain 10 is preferably provided at one end with a ring 11 toreceive the end links of the adjacent chains.

The lower eyes 8 are connected by chains 12 with a pulley 13,-aroundwhich passes the hoisting-chain which extends upward through the opening14 of the top piece or frame 2. As the hoisting cable or chain, which isattached to the upper flexible connections 9, extends downward to thelower connecting devices and has a running engagement or connection withthe same it will be apparent that when there is an upward draft on thehoisting-chain 10 the sides or arms of the grapple will be drawn inwardfrom two points and will be capable of securely grasping a log. Theframe of the pulley 13 is extended below thewheel to form an eye 15,into which the adjacent end links of the chains 12 are linked. The upperend of the hoisting-chain is de signed to be provided with a suitableclevis 16, and it may be secured to any hoisting mechanism.

The invention has the following advantages: The grapple, which is simpleand comparatively inexpensive in construction, possesses great strengthand is capable of securely gripping a log. It is drawn inward intoengagement with a log at both its top and bottom, and the weight of thelog operates to hold the sides or arms of the grapple into engagementwith it. The grapple, which is adapted to be used in connection with anycharacter of hoisting mechanism, may be employed on log-carriers andanalogous devices.

Changes in the form, proportion, and minor details of construction maybe resorted to without departing from the spirit or sacrificing any ofthe advantages of this invention.

What I claim is- 1. Adevice of the class described, comprising a pair ofarms or sides hinged at their upper ends and provided at their lowerends with means for engaging a log, a centrallyarranged flexiblehoisting cable or chain extending downward between the sides or arms,and means for connecting the cable or chain with the sides or arms nearthe top and bottom thereof, whereby the weight of the load will operateto draw the sides or arms into contact with it, substantially asdescribed.

- 2. A device of the class described comprising hinged sides or arms,short chains connected with the sides or arms near the upper endsthereof, a pulley, chains 12 extending from the pulley to the sides orarms and connected with the same near the lower ends thereof, and ahoisting-chain attached to the short chains and passing around thepulley and extending therefrom to the top of the de- Vice, substantiallyas described.

3. A device of the class described, comprising hinged sides or armsprovided at their lower ends with engaging devices, the upper flexibleconnections extending inward from the upper portions of the sides orarms, the lower flexible connecting devices extending inward from thelower portions of the sides or arms, and a hoisting chain or cableattached to the upper flexible connections, extending downward therefromto the lower connecting devices and passing upward therefrom, saidhoisting chain or cable having a running engagement with the lowerconnecting devices, substantially as described.

4. A device of the class described comprising a top piece or framehaving an opening and provided with ears, sides or arms pivoted to theears and provided with spurs or hooks and having eyes near their upperand lower ends, a pulley, a hoisting chain or cable pass ing around thepulley and extending through the opening of the frame or top piece,connections between one end of the hoisting chain or cable and the uppereyes of the sides or arms, and means for connecting the lower eyes ofthe sides or arms with the pulley, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.
